New quartz clock, working intermittently
Brand new quartz clock installed to replace the old one in my 71. The new one works intermittently - not sure why. Power to the plug is good when the clock wasn/t working so must be a ground issue. Would it help if I ran a ground wire to one of the nuts on the back of the new clock?

Yes, it does sound like a ground issue. Try this............when it stops running clamp a ground wire to the gauge bezel and see if it starts running. The gauge bezel is grounded but I don't remember where the ground is but it may be thru the two lower screws that fasten the bezel to the shifter plate. My '71 has a ground wire that attaches to the radio case but I don't know if its the bezel ground.

The ground for the small gauge cluster comes through the temperature gauge connector.
Is this gauge acting up too?
It could also be that the clock screws are not biting into the retainer (ground) good too. You might loosen and then re-tighten them up.

Well I tried all of it and the added ground wire and it still quit working today. It has something to do with starting/shutting down the ignition because it was working til I turned the key... It worked fine the past two days on several ignition cycles then today it decided to stop. Random and frustrating but I'll get over it.
All other gauges are working fine.

you must've gotten the same quartz i returned for the same reason. in the week it was installed, it would run anywhere from 30 seconds to a couple days...and then stop again. bought a second quartz from a different vendor and i have not had to adjust it in 3 yrs...really its that accurate.
